This paper describes an efficient technique for simulating large linear circuits in the time-domain using high-order stable methods. The target area of the proposed technique is in circuit-based simulation of the large linear circuits that arise from full-wave modeling of distributed passive structures such as transmission-lines and microstrip elements. In these applications, the cost of linear system solution typically dominates the computational effort at each time-step. The proposed method takes advantage of the special structure of the block matrices in these applications to reduce the computational cost significantly.
